La obstrucción nasal, rinorrea, descarga posterior, hiposmia y algia facial presentaron una disminución estadísticamente significativa después de la CEN. Además, la encuesta de calidad de vida SNOT-22 reveló una mejora significativa en la calidad de vida de los pacientes después de la cirugía. Conclusión: Este estudio sugiere que la CEN podría tener un impacto significativo en la mejora de los síntomas y la calidad de vida de los pacientes con rinosinusitis crónica. Los resultados de esta cohorte nacional respaldan la efectividad de la CEN como tratamiento para esta enfermedad a largo plazo (1 año) y destacan la importancia de considerar esta opción terapéutica en el manejo de la RSC.
Introduction: Functional endoscopic sinus surgery (FESS) is a widely employed treatment for chronic rhinosinusitis (CRS) and has shown significant benefits in enhancing the quality of life for affected patients. Objective: To assess the impact of FESS on the quality of life in patients diagnosed with chronic rhinosinusitis in a national and longterm cohort (1 year). Material and Method: A prospective cohort study was conducted at the otolaryngology service of Hospital del Salvador between 2017 and 2021, involving 95 patients diagnosed with CRS who underwent FESS. Symptoms such as nasal obstruction, rhinorrhea, posterior discharge, facial pain, and hyposmia were evaluated. The visual analog scale (VAS) was used to measure the cardinal symptoms of CRS, and the SNOT-22 survey was administered before and after the surgical procedure. Results: The study demonstrated a significant improvement in all evaluated symptoms following FESS. Nasal obstruction, rhinorrhea, posterior discharge, hyposmia, and facial pain exhibited a statistically significant decrease. Moreover, the SNOT-22 survey revealed a notable enhancement in the quality of life for patients after surgery. Conclusion: The highlights of this national cohort support the impact of FESS in alleviating symptoms and improving the quality of life for patients diagnosed with chronic rhinosinusitis. The findings provide strong evidence supporting the effectiveness of FESS as a treatment option for CRS and emphasize the importance of considering this surgical approach in the management of this condition.

SUMMARY: In bovines, anatomical observations of the coronary vascular tree describe qualitative characteristics. The objective of this study was to morphometrically characterize the coronary veins and their tributaries in cattle. An arcuate application with 2.0 silk was performed around the ostium of the coronary sinus of 28 bovine hearts and a number 14 catheter was placed, through which semi- synthetic polyester resin and mineral blue color was perfused. In 22 hearts (78.6 %) the great cardiac vein was originated at the cardiac apex. The configuration of the arteriovenous trigone was mainly closed inferior and superior types (50 %). The caliber of the great cardiac vein at the level of the atrioventricular sulcus was 6.7 +/- 1.2 mm. The origin of the left marginal vein was observed in the lower third of the left cardiac margin (53.6 %), its distal caliber was 4.1 +/- 0.8 mm and its drainage was at the level of the great cardiac vein. The middle cardiac vein originated from the cardiac apex in 78.6 % of the samples, emptied mainly into the coronary sinus (82.1 %) and its distal caliber was 4.7 +/- 0.9 mm. Anastomoses occurred in 28.6 % of the hearts, being found in most cases between the middle cardiac vein and the great cardiac vein (50 %), which was significant compared to other anastomoses (p<0.001). The length of the coronary sinus was 42.2 +/- 5.1 mm, its distal caliber was 13.8 +/- 2 mm, and its shape was cylindrical. Myocardial bridges were found in 3 hearts (10.7 %) mainly in the lower third of the middle cardiac vein (66.6 %). Most of the main coronary veins drained into the coronary sinus, with some cases with atypical outlets and the presence of a high percentage of anastomosis that serves to improve cardiac venous drainage in case of venous compression or obstruction.
En bovinos, las observaciones anatómicas de árbol vascular coronario describen características cualitativas. El objetivo de este estudio fue caracterizar morfométricamente las venas coronarias y sus tributarias en bovinos. Se realizó una aplicatura arciforme con seda 2.0 alrededor del ostium del seno coronario de 28 corazones de bovino y se colocó un catéter número 14, a través del cual se perfundió resina de poliéster semisintética y color azul mineral. La vena cardiaca magna se originó en 22 corazones (78,6 %) en el ápex cardiaco. La configuración del trígono arteriovenoso fue principalmente cerrado inferior y superior (50 %). El calibre de la vena cardiaca magna a nivel del surco atrioventricular fue 6,7 +/- 1,2 mm. El origen de la vena marginal izquierda se observó en el tercio inferior del margen izquierdo cardiaco (53,6 %), su calibre distal fue 4,1 +/- 0,8 mm y su desembocadura fue a nivel de la vena cardiaca magna. La vena cardiaca media se originó en el ápex cardiaco en el 78,6 % de las muestras, desembocó principalmente en el seno coronario (82.1 %) y su calibre distal fue 4,7 +/- 0,9 mm. Se presentó anastomosis en el 28,6 % de los corazones, encontrándose en la mayoría de los casos entre la vena cardiaca media y la vena cardiaca magna (50 %), lo cual fue significativo en comparación con otras anastomosis (p<0,001). La longitud del seno coronario fue 42,2 +/- 5,1 mm, su calibre distal fue 13,8 +/- 2 mm y su forma fue cilíndrica. Se encontró puentes miocárdicos en 3 corazones (10,7 %) y en el tercio inferior de la vena cardiaca media (66,6 %). La mayoría de las venas coronarias principales desembocan en el seno coronario, con algunos casos con desembocaduras atípicas y la presencia de un alto porcentaje de anastomosis que sirve para mejorar el drenaje venoso cardiaco en caso de compresión u obstrucción venosa.

ABSTRACT Differentiating orofacial odontogenic pain/disorders from pain/disorders associated with maxillary sinusitis is important to avoid unnecessary dentalprocedures and to properly refer patients to colleagues/dentists and vice versa. Aim To analyze the association between apical lesions and sinus changes and to evaluate the agreement between the diagnoses of an endodontist, a radiologist, an oral and maxillofacial surgeon, and an otolaryngologist. Materials and Method 385 axial, coronal, and sagittal MSCT scans were selected using an image archiving andcommunication system (PACS). The examinations had been performed between 2018 and 2022. Results Apical lesions were observed in 36.10% of sinusitis cases, 73.8% of unilateralsinusitis cases, 48.7% of sinus floor discontinuity cases, and 67.2% of cases in which endodontic treatment had been performed. Agreement between the diagnoses made by the endodontist and those made by the other investigators was high for most study variables (k > 0.60). The exceptions were mucosal thickening, for which agreement between the endodontist and the other investigators was intermediate (k=0.397), and the presence of periapicallesions (k=0.010), previous endodontic treatment (k=0.013), and mucosal thickness (k=0.024), for which agreement between endodontists and radiologists was low. Conclusions: There was an association between sinus changes and apical lesions.

ABSTRACT
ABSTRACT We present an unusual case of a 13-year-old male pediatric patient with a diagnosis of sphenoid sinus mucocele. The patient suffered a progressive loss of visual acuity over three months followed by a total recovery of his visual acuity after surgery. The patient presented at the emergency room complaining of progressive loss of visual acuity in his left eye which decreased to hand motion over the preceding months. Imaging studies revealed a cystic mass, suggestive of sphenoid sinus mucocele, which was causing compressive optic neuropathy and proptosis. The patient was scheduled for a sphenoidectomy and resection of the mass. Three days after surgery, the patient's visual acuity in the left eye was 20/20, indicating complete recovery from his symptoms. We suggest that the excellent outcome in this patient may be attributable to his age. His ongoing physical development might have been the decisive factor in the recovery of his visual acuity following compressive optic neuropathy secondary to sphenoid sinus mucocele. Further research is needed to verify this proposed explanation.
RESUMO Apresentamos um caso incomum de paciente pediátrico com diagnóstico de mucocele de seio esfenoidal, que apresentou perda progressiva da acuidade visual ao longo de três meses, resultando em recuperação total da acuidade visual após a cirurgia. Paciente do sexo masculino, 13 anos, procurou o pronto-socorro, queixando-se de perda progressiva da acuidade visual do olho esquerdo nos últimos três meses. Exames de imagem revelaram uma massa cística sugestiva de mucocele de seio esfenoidal, causando neuropatia óptica compressiva e proptose. O paciente foi agendado para esfenoidectomia e ressecção da massa. Três dias após a cirurgia, a acuidade visual do paciente no olho esquerdo era de 20/20, apresentando recuperação completa dos sintomas. Diante dos resultados de nosso paciente, sugerimos que a idade do paciente pode ser decisiva na recuperação da acuidade visual de uma neuropatia óptica compressiva secundária à mucocele de seio esfenoidal. Mais pesquisas são necessárias para verificação desses dados.
ABSTRACT
Abstract Objective: The aim of this population-based retrospective study was to compare the osteogenic effect of newly formed bone after maxillary sinus floor elevation (MSFE) and simultaneous implantation with or without bone grafts by quantitatively analyzing trabecular bone parameters. Methodology: A total of 100 patients with missing posterior maxillary teeth who required MSFE and implantation were included in this study. Patients were divided into two groups: the non-graft group (n=50) and the graft group (n=50). Radiographic parameters were measured using cone beam computed tomography (CBCT), and the quality of newly formed bone was analyzed by assessing trabecular bone parameters using CTAn (CTAnalyzer, SkyScan, Antwerp, Belgium) software. Results: In the selected regions of interest, the non-graft group showed greater bone volume/total volume (BV/TV), bone surface/total volume (BS/TV), trabecular number (Tb. N), and trabecular thickness (Tb. Th) than the graft group (p<0.001). The non-graft group showed lower trabecular separation (Tb. Sp) than the graft group (p<0.001). The incidence of perforation and bleeding was higher in the graft group than in the non-graft group (p<0.001), but infection did not significantly differ between groups (p>0.05). Compared to the graft group, the non-graft group showed lower postoperative bone height, gained bone height and apical bone height (p<0.001). Conclusion: MSFE with and without bone grafts can significantly improve bone formation. In MSFE, the use of bone grafts hinders the formation of good quality bone, whereas the absence of bone grafts can generate good bone quality and limited bone mass.
ABSTRACT
Objective: To evaluate the clinical response of patients with cystic fibrosis and primary ciliary dyskinesia after endoscopic sinus surgery at the Dr. Robert Reid Cabral Children's Hospital from September 2021 to February 2022. Methods: An ambispective, cross-sectional, observational case series study was conducted, where the study population was made up of patients with cystic fibrosis and primary ciliary dyskinesia at the Dr. Robert Reid Cabral children's hospital during the study period. Inclusion criteria: Patients older than 6 years with a confirmed diagnosis of cystic fibrosis and primary ciliary dyskinesia (Genetic test with 2 homozygous mutations, positives electrolytes in sweat), severe respiratory symptoms of CRS that did not improve with conventional treatment and underwent endoscopic surgery for sinuses. Results: Of a total of 41 patients, only 10 met the inclusion criteria, the most prevalent age range was 14 to 18 years. Both CF and PCD patients decreased the frequency of CRS symptoms. After ENC, there were discrete changes in lung function, and only patients with severe to moderate disease increased % of FEV1. Most of the patients did not require admission after surgery. The most common germ found in nasopharyngeal and sputum cultures in preoperative patients was Pseudomonas aeruginosa in 86%; after ESS there was a significant increase in MRSA colonization in both CF and PCD patients. More than 50% of postoperative patients improved their quality of life, so endoscopic sinus surgery is effective in this population in the treatment of chronic rhinosinusitis.
Objetivo: Evaluar la respuesta clínica de los pacientes con fibrosis quística y discinesia ciliar primaria posterior a la cirugía endoscópica de senos paranasales en el Hospital Infantil Dr. Robert Reid Cabral en el período septiembre 2021 a febrero 2022. Métodos: Se realizó un estudio observacional tipo serie de casos, de corte transversal y ambispectivo, donde la población estudiada estuvo conformada por los pacientes con fibrosis quística y discinesia ciliar primaria del hospital infantil Dr. Robert Reid Cabral en el período de estudio. Criterios de inclusión: Pacientes mayores de 6 años con diagnóstico confirmado de fibrosis quística y discinesia ciliar primaria (Prueba genética con 2 mutaciones homocigotas, electrolitos en sudor positivos), síntomas respiratorios severos de RSC que no mejoraron con tratamiento convencional y sometidos a la cirugía endoscópica de senos paranasales. Resultados: De un total de 41 pacientes, sólo 10 cumplieron con los criterios de inclusión, el rango de edad más prevalente fue de 14 a 18 años. Tanto los pacientes con FQ como los de DCP disminuyeron la frecuencia de los síntomas de RSC. Posterior a la CEN hubo cambios discretos en la función pulmonar, y sólo los pacientes con enfermedad grave a moderada aumentaron el % de FEV1. La mayoría de los pacientes no ameritaron ingresos posterior a la cirugía. El germen más común encontrado en los cultivos nasofaríngeo y esputo en los pacientes preoperatorios fue la Pseudomonas aeruginosa en el 86%, luego de la CEN hubo un aumento significativo de la colonización por MRSA tanto en los pacientes con FQ como en los de DCP. Más del 50% de los pacientes postquirúrgicos mejoraron su calidad de vida, por lo que la cirugía endoscópica de senos paranasales es efectiva en dicha población en el tratamiento de la rinosinusitis crónica.

Abstract Objectives Metabolic Syndrome (MetS) has been established as a significant factor in the pathogenesis of numerous chronic inflammatory conditions. However, its role in Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) is unknown. This study aims to investigate the association between MetS, its components, and the risk of postoperative recurrence in Chinese patients with CRSwNP. Methods A retrospective cohort study was conducted on CRSwNP patients who underwent endoscopic sinus surgery in our hospital. Patients were divided into MetS and non-MetS groups, and the clinical characteristics and recurrence rates were compared. All CRSwNP patients were followed up for more than 2-years and further categorized into non-recurrent and recurrent groups. Binary logistic regression analyses were performed to examine the effects of MetS and its components on the risk of postoperative recurrence. Results A total of 555 CRSwNP patients were enrolled in the present study, 157 patients were included in the MetS group and 398 patients were categorized into the non-MetS group. The recurrence rate in the MetS group was significantly higher compared to the non-MetS group (p< 0.05). The rate of MetS, overweight or obesity, hyperglycemia and dyslipidemia were higher in the recurrent group in comparison with the non-recurrent group (p< 0.05). Multivariate logistic regression analysis suggested that MetS, overweight or obesity, hyperglycemia, dyslipidemia, and accompanying allergic rhinitis were associated with the risk of postoperative recurrence of CRSwNP (p< 0.05). Moreover, adjusted and unadjusted regression models showed that MetS was an independent risk factor for postoperative recurrence of CRSwNP, and the risk increased with more components of MetS included (p< 0.05). Conclusion Our findings revealed that MetS independently increased the risk of postoperative recurrence in patients with CRSwNP, with the risk escalating as the number of MetS components increased. Moreover, accompanying allergic rhinitis was also demonstrated to be a potential risk factor for CRSwNP recurrence. Level of evidence: Level 4.
ABSTRACT

ABSTRACT
Abstract Introduction The advent of the endoscope has enabled the use of the endonasal approach for a variety of diseases. Studying the ethmoidal canals is important for surgeries of the paranasal sinuses and the anterior base of the skull. Objective To investigate the ethmoidal canals and evaluate their structure, the presence of vessels and nerves, their location, and to perform an anatomopathological study of their contents. Methods We evaluated 20 cadavers (20 left and 20 right nasal cavities) through endoscopic dissection of the anterior base of the skull and exposure of the medial periorbita and dura mater; then, the ethmoidal canals were located and measured in relation to the anterior wall of the sphenoid sinus and between the ethmoidal canals, followed by removal of their content for histological analysis. Results Vessels were present in 75% of the left anterior ethmoidal canals, 70% of the left posterior ethmoidal canals, 75% of the left middle ethmoidal canals, 85% of the right anterior ethmoid canals, and 64.5% of the right posterior ethmoid canals; 50% of the right middle ethmoidal canals contained one vessel. Conclusion The ethmoidal canal does not necessarily contain an ethmoidal artery. Studies with a larger sample should be performed to quantify the correct proportion of arteries and ethmoidal canals.
ABSTRACT
Abstract Introduction Jet aircraft pilots are exposed to huge pressure variation during flight, which affect physiological functions as systems, such as the respiratory system. Objectives The objective of the present investigation was to evaluate inflammatory changes of paranasal sinuses of jet aircraft pilots before and after a jet aircraft training program, using multislice computed tomography (CT), in comparison with a group of nonairborne individuals with the same age, sex, and physical health conditions. A second objective of the present study was to assess the association between the ostiomeatal complex obstruction and its anatomical variations. Methods The study group consisted of 15 jet aircraft pilots participating in the training program. The control group consisted of 41 nonairborne young adults. The 15 fighter pilots were evaluated before initiating the training program and after their final approval for the presence of inflammatory paranasal sinus disease. The ostiomeatal complex anatomical variations and obstructions were analyzed in pilots after the training program. Results Jet aircraft pilots presented higher incidence of mucosal thickening in maxillary sinus and anterior ethmoid cells than controls. Prominent ethmoidal bulla showed significant association with obstruction of the osteomeatal complex. Conclusions Jet aircraft pilots present increased inflammatory disease when compared with nonairborne individuals. The presence of a prominent ethmoidal bulla is associated with ostiomeatal complex obstruction.
ABSTRACT
Las extrasístoles ventriculares (EEVV) son frecuentemente asintomáticas y no requieren de tratamiento antiarrítmico. Las EEVV de los tractos de salida son las EEVV idiopáticas más frecuentes en la práctica clínica. La anamnésis, el examen físico y el electrocardiograma son fundamentales en el diagnóstico. Aunque las EEVV de los tractos de salidas ventriculares son consideradas benignas, pueden producir diversos síntomas y desencadenar una cardiomiopatía inducida por las extrasístoles, que lleva a un deterioro de la función sistólica ventricular izquierda y en última instancia, insuficiencia cardiaca. Cuando el tratamiento farmacológico de las EEVV fracasa, nos queda la ablación de arritmias por catéter de radiofrecuencia como única alternativa eficaz. Este es el caso de la paciente de sexo femenino de 62 años, hipertensa, dislipidémica y tabaquista, que demuestra la seguridad de la ablación por catéter de radiofrecuencia, la eficacia terapéutica, y el restablecimiento integro de la función ventricular del corazón.
Premature ventricular complexes (PVC) are frequently asymptomatic and do not require antiarrhythmic treatment. Outflow tract PVC are the most common idiopathic PVC in clinical practice. The anamnesis, physical examination and electrocardiogram are essential in the diagnosis of these patients. Although PVC of the ventricular outflow tracts are considered benign, they can produce various symptoms such as dyspnea on exertion, asthenia, palpitations, dizziness, presyncope or syncope, and in those patients with very high arrhythmic burden (>24% on a 24-hour Holter monitoring), can trigger extrasystole-induced cardiomyopathy, leading to deterioration of left ventricular systolic function and ultimately heart failure. When pharmacological treatment of PVC fails, ablation of arrhythmias by radiofrequency catheter is the only effective alternative. This is the case of the 62-year-old female patient, hypertensive, dyslipidemic and a smoker, which demonstrates the safety of radiofrequency catheter ablation, the therapeutic efficacy, and the complete restoration of the ventricular function of the heart.
ABSTRACT
Objetivo: O objetivo do estudo foi avaliar a prevalência de variações anatômicas no complexo nasossinusal por meio de tomografia computadorizada (TC) em pacientes com sinusite não odontogênica. Métodos: Um estudo observacional e retrospectivo consistiu em 860 prontuários com indicação de tomografias computadorizadas multislice para avaliação de sinusite. A sinusite odontogênica foi caracterizada pela presença de espessamento da mucosa sinusal maior que 2 milímetros e ausência de alterações dentárias na região. Posteriormente, foram avaliadas as variações do complexo nasossinusal e realizada uma análise descritiva. Em seguida, 33 tomografias computadorizadas foram analisadas com sinusopatia não odontogênica, e o complexo nasossinusal foi avaliado quanto à presença das seguintes variações anatômicas como desvio do septo nasal associado a esporão ósseo, concha média bolhos, aumento do seio frontal entre outras. Resultados: Variações anatômicas foram observadas em 87,9% dos casos, sendo 15 do gênero masculino (46,0%) e 18 do gênero feminino (54,0%) e distribuídos em 45,5% dos pacientes entre 41-60 anos. A variação anatômica mais frequente foi a concha média bolhosa (37,9%), seguida de septações no seio maxilar (10,3%) e seio frontal alargado (13,8%). Conclusão:Verificou-se uma considerável incidência de variações anatômicas associadas à sinusite não odontogênica, com evidência para a concha média bolhosa.
Aim: The aim of the study was to assess the prevalence of anatomical variations in the sinonasal complex using computed tomography (CT) in patients with non-odontogenic sinusitis. Methods: This observational and retrospective study involved the analysis of 860 multislice CT scans prescribed for sinusitis evaluation. Non-odontogenic sinusitis was characterized by the presence of sinus mucosal thickening exceeding 2 millimeters and the absence of dental changes in the region. Subsequently, sinonasal complex variations were evaluated, and a descriptive analysis was conducted. Subsequently, 33 CT scans with non-odontogenic sinusopathy were analyzed, and the sinonasal complex was evaluated for the presence of the following anatomical variations: deviation of the nasal septum associated with a bony spur, bullous middle concha, unilateral hypoplasia of the maxillary sinus, among others. Results: Anatomical variations were observed in 87.9% of cases, with 15 males (46.0%) and 18 female (54.0%), distributed among patients aged 41-60 years (45.5%). The most frequent anatomical variation was the bullous middle concha (37.9%), followed by septations in the maxillary sinus (10.3%) and enlarged frontal sinus (13.8%). Conclusion: A considerable incidence of anatomical variations associated with non-odontogenic sinusitis was observed, with evidence of a bullous middle concha.

Abstract Background Increasing evidence suggests that inflammatory biomarkers play a significant role in cerebral venous sinus thrombosis (CVST). The neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and monocyte-to-lymphocyte ratio (MLR) are related to thrombotic conditions and indicators of systemic inflammation. Objective To analyze the correlation between inflammatory biomarkers and the extent of thrombus, determined by the CVST-Score. Methods A total of 40 patients with CVST (24 female subjects; 60%) and 40 age- and sex-matched healthy controls were retrospectively evaluated. Inflammatory biomarkers, including C-reactive protein (CRP), PLR, NLR, MLR, and the CVST-Score, were recorded to assess the relationship between biomarkers and thrombus burden. The patients were grouped according to symptom duration (group 1: 0-3 days; group 2: 4-7 days; and group 3: 8-30 days) to compare biomarker levels. Results The CRP, NLR, and PLR were significantly higher in the CVST group (p< 0.001; p= 0.003; p= 0.014 respectively). The NLR and PLR presented a significant positive correlation with the CVST-Score (p= 0.003, r = 0.464; p= 0.040, r = 0.326 respectively). The NLR was significantly higher in group 1 compared with groups 2 and 3 (p= 0.016 and p= 0.014 respectively). In group 1, there was a stronger positive correlation between the CVST-Score and the NLR (p= 0.026, r = 0.591) and the PLR (p= 0.012, r = 0.648). The multiple linear regression analysis revealed that the NLR is a key factor in predicting the CVST-Score (p= 0.019). Conclusion The NLR and PLR are associated with thrombus burden in CVST, especially in patients admitted to the hospital in the early stages. The NLR is an independent factor to predict the thrombus burden in CVST.
Resumo Antecedentes Há evidências crescentes de que biomarcadores inflamatórios desempenham um papel importante na trombose venosa cerebral (TVC). A razão neutrófilo-linfócito (NLR), a razão plaqueta-linfócito (PLR) e a razão monócito-linfócito (MLR) estão relacionadas a condições trombóticas e são indicadores de inflamação sistêmica. Objetivo Analisar a correlação entre NLR, PLR, MLR e a extensão do trombo, determinada pelo escore de TVC. Métodos Avaliamos retrospectivamente 40 pacientes com TVC (24 mulheres; 60%) e 40 controles pareados por idade e sexo. Biomarcadores inflamatórios, incluindo proteína C reativa (PCR), PLR, NLR, MLR e escore de TVC, foram registrados para avaliar a relação entre biomarcadores e carga trombótica. Os pacientes foram agrupados de acordo com a duração dos sintomas (grupo 1: 0-3 dias; grupo 2: 4-7 dias; e grupo 3: 8-30 dias) para a comparação dos níveis de biomarcadores. Resultados A PCR, a NLR e a PLR foram significativamente maiores no grupo com TVC (p< 0,001; p= 0,003; e p= 0,014, respectivamente). A NLR e a PLR apresentaram correlação positiva significativa com o escore de TVC (p= 0,003, r = 0,464; e p= 0,040, r = 0,326, respectivamente). A NLR foi significativamente maior no grupo 1 em comparação aos grupos 2 e 3 (p= 0,016 e p= 0,014, respectivamente). No grupo 1, houve correlação mais forte entre o escore de TVC e a NLR (p= 0,026, r = 0,591) e a PLR (p= 0,012, r = 0,648). A análise de regressão linear múltipla identificou a NLR como fator-chave na predição do escore de TVC (p= 0,019). Conclusão A NLR e a PLR estão associadas à carga trombótica na TVC, especialmente em pacientes admitidos precocemente, e a RNL é um fator independente na previsão da carga trombótica.
ABSTRACT
Bipolar affective disorder refers to a category of mood disorders characterized clinically by the presence of both manic or hypomanic episodes and depressive episodes.Lithium stands out as the primary pharmacological intervention for managing bipolar affective disorder.However,its therapeutic dosage closely approaches toxic levels.Toxic symptoms appear when the blood lithium concentration surpasses 1.4 mmol/L,typically giving rise to gastrointestinal and central nervous system reactions.Cardiac toxicity is rare but serious in cases of lithium poisoning.The study reports a case of a patient with bipolar affective disorder who reached a blood lithium concentration of 6.08 mmol/L after the patient took lithium carbonate sustained-release tablets beyond the prescribed dosage daily and concurrently using other mood stabilizers.This resulted in symptoms such as arrhythmia,shock,impaired consciousness,and coarse tremors.Following symptomatic supportive treatment,including blood dialysis,the patient's physical symptoms gradually improved.It is necessary for clinicians to strengthen the prevention and recognition of lithium poisoning.

Objective To investigate the efficacy of Amplatzer duct occluder-Ⅱ device(ADO-Ⅱ)in treating ventricular septal detect(VSD)with aortic sinus prolapse(ASP)in child patients.Methods The clinical data of 94 child patients with VSD complicated by ASP,who were admitted to the Hunan Provincial Children's Hospital of China between January 2018 and September 2022,were retrospectively collected.The child patients included 60 males and 34 females with a mean age of(4.7±3.1)years.Mild-moderate ASP was seen in 83 child patients,with a mean(4.12±0.97)mm-sized VSD.Severe ASP was seen in 11 child patients,with a mean(4.95±0.51)mm-sized VSD.Perimembrane VSD was observed in 54 child patients and intracristal VSD in 40 child patients.The relationship of VSD size and degree of ASP to the selection of ADO-Ⅱ,postoperative middle period aortic valve regurgitation and residual leakage was analyzed,so as to clarify the applicability of ADO-Ⅱ to such child patients.Results In the postoperative middle period,6 child patients had mild aortic valve regurgitation,most seen in the child patients who received 4-4 mm or 5-4 mm ADO-occluder;and 10 child patients had residual leakage,mainly seen in the child patients who received 5-4 mm or 6-4 mm occluder.Conclusion In the condition when the ADO-Ⅱ occluder shows satisfactory placement pattern,this treatment is suitable for the child patient having<6 mm VSD with ASP.Although there are some residual leakage and aortic valve regurgitation after surgery,this interventional therapy still meets the clinical requirements.(J Intervent Radiol,2024,32:17-21)
ABSTRACT
Objective:To explore the value of ultrasound measuring gastric sinus cross-sectional area (CSA) to guide early individualized enteral nutrition implementation strategies in sepsis patients.Methods:Thirty septic patients admitted to the EICU and comprehensive ICU of The Second Affiliated Hospital of Nanjing University of Chinese Medicine between January 2021 and December 2022 each were included. EICU patients used bedside ultrasound for gastric sinus CSA to guide the implementation of early enteral nutrition in septic patients, and a routine nutritional support strategy was adopted in the integrated ICU. The correlation of CSA and feeding intolerance in patients with septic gastrointestinal dysfunction, the ROC curve and other relevant indicators of gastrointestinal dysfunction gastrointestinal dysfunction score, SOFA score, APACHEⅡ score, intra-abdominal pressure (IAP), serum protein (PA), [albumin (Alb)]. By comparing the indicators related to inflammation, nutritional status and days of ICU stay after different strategies of the two groups, the advantages of different strategies were analyzed.Results:The baseline data of the two groups were balanced and comparable; the incidence of feeding intolerance was significantly higher (36.67%) than the conventional group (10.00%), with aggressive and early individualized treatment, the incidence rate on the third day was only 10.00%, significantly lower than that in the conventional treatment group (40.00%). Treatment up to the 5th day, the related function scores (gastrointestinal dysfunction score, APACHEⅡ score, SOFA score, IAP), nutritional status indicators (5 d hot card reaching the standard rate, PA, Alb) and inflammation indicators (WBC, PCT, hs-CRP) were significantly improved compared with admission, and is better than the conventional treatment group. In addition, the ICU hospital days and the incidence of aspiration were lower in the ultrasound treatment group ( P <0.05). CSA showed favorable correlation with gastrointestinal dysfunction score, APACHEⅡ score, SOFA score, IAP, PA and Alb, correlation coefficients were 0.79、0.60、0.66、0.71、-0.6 and -0.64( P <0.05). The ROC curve for predicting feeding intolerance by CSA showed the AUC was 0.828, 95% CI was 0.737-0.919, its optimal cutoff value for predicted feeding intolerance was 7.835 cm 2, the sensitivity and specificity were 88.20% and 71.80%. Conclusions:Ultrasound measuring CSA can early and effectively found the feeding intolerance in the patients with sepsis , via giving individualized enteral nutrition implementation strategy, significantly improve the organ function score, nutritional status and inflammation index, reduce the ICU hospital days and aspiration, and correlate with the conventional evaluation index, and sensitivity and specificity are high, worthy of the clinical further promotion.
ABSTRACT
Objective To investigate the CT and MRI findings of different types of small round cell tumor(SRCT)in the nasal cavity and sinuses.Methods A retrospective analysis was conducted on the imaging data and clinical data of 35 SRCT patients confirmed by pathology.Thirty-one SRCT patients underwent CT examination,and 19 SRCT patients underwent MRI examination.Results There were 20 cases of tumors that invaded the nasal cavity and 19 cases involved the sinuses,including 11 cases of the maxillary sinus,7 cases of the ethmoid sinus,2 cases of the sphenoid sinus,and 1 case of the frontal sinus.CT findings of SRCT were all soft tissue masses.Lymphoma was relatively homogeneous with mild bone destruction,and usually involved nasal vestibular skin.Rhabdomyosarcoma(embryonic type)happened at an early age and easily caused bone destruction and metastasis.Melanoma generally occurred in the nasal septum and nasal cavity,which was prone to bleeding.Small cell neuroendocrine carcinoma was heterogeneous,with moderate to significant enhancement,bone absorption and destruction were often noticed.The MRI manifestations of SRCT were equal or long signal on T1WI,high signal on T2WI,and significant diffusion limitation on diffusion weighted imaging(DWI)and apparent diffusion coefficient(ADC)except for melanoma.On contrast-enhanced images,lymphoma showed mild to moderate enhancement,rhabdomyosarcoma showed typical"grape sign",and small cell neuroendocrine carcinoma showed"sieve"and"map-like"obvious enhancement.Typical melanoma showed a high signal on T1WI and a low signal on T2WI and usually caused bleeding.The MRI findings were related to the presence of melanoma and hemorrhage within the lesion.Conclusion SRCT of the nasal cavity and sinuses have a high degree of malignancy and poor prognosis,CT and MRI have many similar manifestations.Combining clinical data,bone destruction,MRI enhancement,and DWI sequence can effectively distinguish different types of SRCT,as well as squamous cell carcinoma of the nasal cavity and sinuses and adenoid cystic carcinoma.
ABSTRACT
@#Acute Stanford type A aortic dissection has the characteristics of acute onset, severe condition and high mortality. Once making a definite diagnosis, surgical treatment is needed as soon as possible. It is difficult for cardiac surgeons to treat the acute aortic dissection involving the aortic sinus, which is an important risk factor for death. Improving the surgical treatment for the aortic sinus can be a key to improving the prognosis. In this review, we will introduce the modified sandwich technique for acute Stanford type A aortic dissection and the prognosis, and summarize the experiences of different modified sandwich techniques. However, there is still no unified standardized technique in aortic root repair, and there is a lack of large studies with long-term follow-up, so it is necessary to further improve the aortic root repair techniques.
ABSTRACT
Objective@#To analyze the spatial relationship between the roots of maxillary anterior premolars and the maxillary sinus, thus providing an anatomical basis for timing, planning, surgical approaches, and implant selection at this site.@*Methods@#Cone beam CT (CBCT) images were collected from 264 patients (aged 20-65 years) who visited the Ruihua Dental Clinic between January 2017 and March 2023. The minimum distance from the apex of the maxillary anterior premolar roots to the lower wall of the maxillary sinus was measured on the coronal plane. The classification of the vertical relationship between the tooth root and the lower wall of the maxillary sinus was performed, and comparisons were made bilaterally, between genders, and among different age groups.@*Results@#The minimum distance (Q50) from the apex of the first maxillary premolar root to the lower wall of the maxillary sinus was 7.34 mm for the single-root type, 7.80 mm for the buccal root of the double-root type, and 7.36 mm for the palatal root. For the second maxillary premolar, the median distance was 2.56 mm for the single root type, 1.73 mm for the buccal root type, and 1.23 mm for the palatal root type. There was a significant difference in the shortest distance from the apex of the right second maxillary premolar single root to the lower wall of the maxillary sinus among the different age groups (P<0.05), with the 20-29-year-old group having the smallest median distance (1.52 mm) and the ≥ 40-year-old group having the largest (4.44 mm). There was no significant difference in the effect of sex or laterality on distance (P>0.05). The most common vertical relationship between the apex of the maxillary anterior premolar roots and the lower wall of the maxillary sinus was noncontact. There was no significant difference in the vertical relationship classification between the single-root and double-root types (P>0.05).@*Conclusion@#Most maxillary first premolar roots can provide sufficient bone height, which makes it easy to achieve immediate implantation. The maxillary second premolar root frequently involves insufficient bone, which is necessary to make full use of the bone wall of the extraction socket or the sinus floor cortical bone to achieve initial stability. The vertical relationship between the premolar root and maxillary sinus was influenced by age and dental position. Younger age groups often exhibit inadequate bone height, and the indication for immediate implantation should be carefully considered. The number of roots does not significantly affect the relationship between the sinus and root; however, double-rooted premolars offer more support for immediate implantation and socket healing due to the small root diameter and bony separation between the roots.
ABSTRACT
Objective@#To assess the depths of the anterior epitympanic recess (AER) and the sinus tympani (ST) among Filipino adults and to classify the AER and ST according to grade and type, respectively.@*Methods@#Design:Retrospective Review of CT ScansSetting:Tertiary Private Teaching Hospital Participants: Scans of 182 non-pathologic ears from patients aged 18 and above with non-pathologic temporal bones (paranasal sinus, screening sinus, temporal bone, facial and cranial) with 0.62mm cuts seen from CT scans from January 01, 2010 to September 31, 2022 were analyzed. The depths of the AER and ST were measured separately and classified according to AER grade and ST type.@*Results@#The mean depth of the AER (AER-D) was 3.64 mm (SD 1.17). No significant difference was seen between right and left ears. The AER grading of the anterior-posterior depth was found to be Grade 1 (<3mm) in 54 ears (29.7%), Grade 2 (3-5mm) in 106 ears (58.2%), and Grade 3 (>5mm) in 22 ears (12.1%). The mean depth of the sinus tympani (ST-D) was 3.30 mm (SD 0.80). Out of the 182 ears, 121 (66.5%) had Type A, 50 (27.5%) had Type B while 11 (6%) had Type C.@*Conclusion@#Majority of the AER depths measured 3-5mm while most of the sinus tympani were Type A. These hidden recesses should be separately analyzed in preoperative planning for cholesteatoma surgery in order to prepare the adequate equipment to be used and approach towards these areas thereby reducing the risk for residual cholesteatomas and recurrence.
